SAW-GUIDE.

SPECIFICATION formiug part of Letters Patent-(No. 591,185, dated October 5, 1897.

I Application filed January 11, 1897. Serial No. 618,?3'70- (No model.)

To all whom it may concern: Be it known that I, FRED CLUFF, of Mar,

' in the county of Bruce and Province of Ontario, Canada, have invented certain new and useful Improvements in Saw-Guides, of which the following is a specification.

The object of my invention is to devise a saw-guide for right or left hand frames in which the guides are not only adjustable independently, but may also be adjusted simultaneously to regulate the lead of the saw; and it consists, essentially, of guides adjustable in a head which is itself adjustable on a baseplate, the guides and their means of adj ust ment being made reversible, substantially as hereinafter more particularly described, and then definitely claimed.

Figure 1 is a perspective view of my im proved saw-guide. Fig. 2. is a plan View of the under side of the base-plate, showing the means of adjusting the head carrying the guides. Fig. 3 is a cross-section through the lines as y in Fig. 2.

In the drawings like letters of reference in dicate corresponding parts in the different figures.

A is a portion of the frame of the machine to which the guide is applied.

B is a base-plate connected to the frame A by means of bolts a, passing through slots so that the position of the base-plate may be readily adjusted.

C is a head having afianged foot D, adapted to slide in guides E, formed on or bolted to the base-plate l3.

Fis a diagonal groove formed in the lower side of the flanged foot D of the head C.

G is a slide having a diagonal portion 12, formed thereon to fit the groove F, and a straight portion 0 to fit a straight slot e in the base-plate B.

From this construction it will be seen that by moving the slide Gr longitudinally a transverse motion will be given to the head 0. For the purpose of imparting motion to the slide G, I provide a screw-threaded rod H, which screws into a similarly-threaded hole in the straight portion 0 of the slide Gr. The other end of this rod is provided with a handwheel I and has a coarse left-handed thread thereon which engages with a similarly-cut thread Within the lug f. Thus by revolving the hand-Wheel I not only will the rod H be screwed into the slide G, but the rod itself will be screwed outwardly through the lug f, and thus a quick motion will be imparted to the said slide. Though I prefer to screw therod H through the lug f, as shown, yet a simple thrust-bearing of any construction might be substituted.

J are the saw-guides of ordinary construction, having their stems g sliding in suitable holes formed within the head C. The other ends of these stems are preferablyreduced in sizeand screw-threaded to receive the adjusting-nuts K. These nuts are held from endwise motion by being set between the head and a strap L, the ends of which are bolted in recesses h, formed. in the sides of the head and provided with similarly located boltholes. From this construction it follows that by turning the adj Listing-nuts K endwise motion will be imparted to the stems g and the saw-guides J moved as may be desired.

It will be noticed that the recesses h h are formed at the opposite ends of the head 0. This enables me to adapt the same guide to right or left hand frames. By removing the strap L and the'adjusting-nuts K the stems g of the guides may be removed from the head and inserted into it again from the other side. The adjusting-nuts are then replaced and the strap placed in position on the opposite side of the head with its ends in the recesses h.

M are set-screws for clamping the guides J when adjusted.

From the above descriptionit will be seen that I have devised a saw-guide in which the guides are not only separately adjustable to suit the saw, but may be also moved simultaneously to regulate the lead of the saw as may be desired. Theguide is also readily adaptable, as previously explained, to suit right or left hand frames.

What I claim as my invention is-- In a saw-guide, the combination of the head 0, having recesses h, h, and similarly-located bolt-holes formed therein; the guides J, provided with stems g; the strap I1; and the adj usting-nuts K, substantially as and for the purpose specified.
